“…The increase of seeds number, setting the water volume, provides increase of electrical conductivity value (Tables 3 and 4). Pereira et al (2015) observed the same, what means, the electrical conductivity value increased when a higher number of seeds was used in the test. However, Lopes et al (2010) did not observed electrical conductivity increasing by increasing seeds number.…”

This study aimed to evaluate the physiological performance of white clover seed lots of different tegument colours, besides to analyses the electrical conductivity test methodology with different seeds number, water volume and soaking periods. The experiment was developed at the Seed Didactic Laboratory in the Agronomy College “Eliseu Maciel” at the Federal University of Pelotas, in Pelotas-RS, Brazil. White clover seeds were manually separate, composing four lots of different coloured seeds: yellow, orange, brown and mixed. White clover seeds of yellow colour tend to present greater physiological potential through its germination and vigour. The electrical conductivity test was not efficient on identifying different vigour levels in white clover seed lots.

“…Com base nos resultados supramencionados, usou-se a temperatura de 25ºC para a comparação com o teste de condutividade elétrica, por causa da sua superioridade nos testes de vigor. Esse teste tem servido para avaliar a qualidade fisiológica de muitas espécies florestais (PEREIRA & MARTINS FILHO, 2012;TARGINO et al, 2015;DELAZERI et al, 2016;OLIVEIRA et al, 2016).…”

A principal forma de propagação de Schinus terebinthifolius é por sementes, contudo pouco se conhece sobre os testes para a avaliação da qualidade fisiológica das sementes dessa espécie. Os objetivos do presente trabalho foram avaliar a influência da temperatura no teste de germinação em sementes de S. terebinthifolius e verificar a eficiência do teste de condutividade elétrica. Sementes de três lotes foram submetidas a teste de germinação nas temperaturas de 20ºC e 25ºC e a testes de vigor: índice de velocidade de germinação, tempo médio de germinação, comprimento de plântula e condutividade elétrica, com leituras após 0, 2, 4, 6, 8, 10, 12, 24, 26 e 28 horas de embebição. Obtiveram-se plântulas mais vigorosas e resultados superiores para o índice de velocidade de germinação, tempo médio de germinação e comprimento de plântulas na temperatura de 25ºC. No teste de condutividade elétrica, após 10 horas de embebição, as leituras foram estabilizadas e permitiram a comparação entre lotes. A temperatura de 25ºC é mais adequada para a condução do teste de germinação de sementes de S. terebinthifolius, e o teste de condutividade elétrica não é recomendado para a análise da qualidade fisiológica das sementes de tal espécie.

“…Water absorption curve and electrical conductivity: four replications with 50 seeds of each treatment were used, and the weight of each replication was measured on a precision analytical scale (0.001 g). Then, the seeds were put into properly identified plastic cups containing 75 mL of distilled water and placed in germination chamber, at 25 °C, with 12 h photoperiod (Pereira et al, 2015).…”

Atmospheric plasma overcomes dormancy of Pityrocarpa moniliformis (Benth.) Luckow & R. W. Jobson seeds

et al. 2022

Atmospheric plasma application technology consists of a fast and practical method, which has the potential to modify the surface of seeds with integumentary hardness. The aim of this research was to evaluate the effect of applying atmospheric cold plasma on Pityrocarpa moniliformis seeds, assessing its implications on the seed coat impermeability, germination and vigor. Cells were subjected to plasma for 1.5, 2.0, 3.0, 4.0 and 5.0 minutes, using seeds without any treatment as a control. After application, the seed coat wettability, imbibition curve and electrical conductivity of the soaking solution were determined. Seeds were also subjected to the germination test, and its results were used to determine viability, median, uniformity and asymmetry of germination. Seeds subjected to plasma for 5.0 and 4.0 minutes showed the lowest apparent contact angles, 64 and 61°, respectively, characterizing greater wettability of the seed coat among the treatments tested. Higher germination was observed in the treatments with plasma application when compared to the control. Atmospheric plasma application technology has the potential to be used as an accelerator of P. moniliformis seed germination.
